B-LINE 42MC – Frequently Asked Questions
1) What is the Eaton B-Line 42MC mounting channel used for inside an enclosure?
The 42MC is a mounting channel for Eaton B-Line Premier series enclosures. It is used to build vertical or horizontal framework inside the box, so panels, DIN rail, subplates and components get bolted to the channel instead of drilling the enclosure shell. Building the framework first also keeps the enclosure walls unpunctured, which is what preserves the NEMA 4X rating on the enclosure.
2) Is the 42MC channel rated for washdown or outdoor enclosures?
It carries a NEMA 4X degree of protection, which is the washdown and corrosion-resistant class, and it is cUL Listed. NEMA 4X is the rating you want where the enclosure sees hosedown, coolant spray or corrosive atmosphere rather than just dust.
3) What finish and material is the B-Line 42MC, and will it hold up in a damp room?
Zinc plated steel channel. Zinc plating is the normal choice for interior enclosure framework and for damp or humid rooms; for continuous chemical immersion or a marine deck, stainless framework is the better call.
4) What size is the 42MC mounting channel?
The published dimension on the 42MC is 42 inches, and it weighs .892 lb. The model designation follows that length, so if you are laying out a 42 inch tall or wide enclosure bay, one channel spans it without splicing.
5) Do I order the 42MC channel by itself or does it come with the mounting hardware?
Order is by model 42MC, a single channel. The channel is the framework member only, so plan on the Premier series clips, brackets and fasteners that tie it to the enclosure and carry your subpanel. Quantity is driven by how many vertical and horizontal runs your layout needs.
6) Can the same channel run horizontally, or do I need a different part for cross members?
One part covers both. The 42MC is intended to create vertical or horizontal framework, so the same channel serves as an upright or a cross member depending on how you mount it.
7) Is the 42MC a Canadian-listed part for a panel build going into Canada?
Yes, it is cUL Listed, which is the Canadian listing an inspector looks for on enclosure framework in a panel shipping north.
